A regulator matches its gas and its cylinder. The gas names the type, oxygen and argon regulators here at 300 bar alongside industrial bottle regulators in single and double gauge forms, and the cylinder names the thread: disposable bottles take their own regulators, listed with no gauge or one gauge, because the disposable thread differs from refillable cylinder fittings.
Gauges are the second choice. A single gauge reads the cylinder contents, a double gauge adds the working pressure at the outlet, and the disposable types run gaugeless or single because their bottles are read by weight. Every listing states its gas, thread and gauge count, so the three answers pick the regulator.
Hose follows the gas by colour and bore: oxygen in blue, acetylene in red, propane in orange, the convention that keeps flame gases apart, in ten metre lengths at 6mm and 10mm bores, with braided MIG hose in 6mm and 8mm for the shielding side and the 56014 regulator hose replacing perished tails on SIP sets. The 300 bar rating on the regulators is the cylinder pressure they accept, full industrial bottles arriving at that pressure and the regulator stepping it down to working figures. In line flashback arrestors, fuel and oxygen types, sit between regulator and hose on flame systems as the one way valve that stops a flame travelling back.
The corner pieces solve the setups: the AK9 adaptor hose converts a MIG welder from disposable bottles to an industrial gas supply, regulator hoses replace perished tails, and the cylinder safety cage stores four 19kg bottles outside.
